GRINDING DEVICE.

Application filed February 21, 1920.

To all whom it may concern:

Be it known that l, HUGO'E. RosnnKRANz, a citizen of the United States, and resident oi Oshkosh, in the county oi l vinnebago and State of Wisconsin, have" invented new and useful Improvements in Grinding Devices, of which the following is a description, reference being had to the accompany ing drawings, which are apart or this specification.

The present invention relates to certain new and useful inprovements in grinding devices and refers more particularly to a device of this character especially adapted for use at soda fountains or the lilre places for comminuting nuts for use in connection with the special dishes dispensed atsuch tountains. i

One object of the present invention is to provide a'neat and compact grinding device nuts and provided with means whereby the nuts may be ground when desired Another object of this invention is to provide a grinding device of the class described so constructed that the same may be readily taken apart for the purposeot clcaningrto prevent the oil from the same from becoming rancid and spoiling the materials.

A further object of this invention is to provide improved cutting means whereby the positive feeding of the material within the container to the cutter is insured.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawing 1 have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and inwhich:

Figure 1 is a perspective view of my complete device illustrating the same as in operative position.

Figure 2 is a side view of my device, the material container being only partly shown and parts of the grinder proper being Serial 15o. 369,354.

broken away and in section to more clearly illustrate structural details, and

V Figure 3 is a view part in section and part in elevation taken on the plane indicated by the line 33 of Figure 2.

Referring now more particularly to the accompanying drawing, my improved device consists of an upper section 5, and'a lower section 6, the upper section 5 providing a feed hopper and having its upper end in-. ternally threaded as at 7 to receive the lower threaded end 8 of a globular container 9 preferably of glass.

The lower end of the section 5 is closed by two longitudinally extending walls 10 inclined downwardly toward each other and having their inner-ends spaced a slight distance apart to provide an opemng 11 communicating the section 5 with the section 6.

Suitable grinding means are positioned in the section 6 adjacent the opening 11 for comminuting the material within the section 5 as the same is fed through the open- .ll'lg 11.

The grinding means consist of two complementary cutting members 12 secured to a shaft 13 journalled in the lower section 6 drawn through the center of the cutter, and

the space between the teeth or each series is sutiicient to permit the material within the hopper section 5 and the container 9 to be properly fed to the cutter.

As best shown in Figures 2 and 3, the cutting teeth of one cutter are staggered with relation to the cutting teeth of the other so that the material within the hopper 5 and the container 9 will be fed evenly therefrom and maintain the material within the container 9 substantially level. The cutters are secured to the shaft 12 by means of set screws or the like 16 and have a locking connection between each other by means of lugs 17 formed on one cutter and engaging in recesses 18 formed in the other cutter. The recesses 18 and lugs 17 are so positioned that the cutters may be arranged with their teeth inthe position depicted in FiguresQ and 3 or with the teeth of each cutter substantially in: alignment. 7

The wall of the section 6 is inclined inwardly at its lower end as atl9 to provide a restricted discharge opening 20, through which the ground or comminuted nuts or other materials are discharged The shaft 1 3, and with it the cutter 12, is rotated by means of a hand crank 21 secured to one end of the shaft which is projected beyond the lowersection 6. Ihe other end of the shaft 13 is secured in place by a screw or other fastening 2-2 whereby the same may be readily removed from the section;

As best shown vin Figures 1 and 3, my-

grinding device is secured to a wall or other base (not shown) by means'of' a substantially Vshaped support 23 having its outer ends bent laterally to provide securing means 24 and having the apex oi the V flattened as at 25cand secured to. the section 6 by means of fastenings 26,,see Figure 3.

' As besteshown in Figures 2 and 3, the section 5lias itsrlower portion reeueed as at 27 andtele'scoped' within theupper portion of "section Gandsecured thereinbym'eans of suitable tastenings 28- This structure permits my device to be readily taken apart for the purpose ofcleaning' as will be readily apparent;

hat I? claim as my invention is:

1. A grinding device comprising a container, a partition therein including two opposed downwardly inclined walls proj ecting towardthe center oft-he container and hav-' ing their inner ends'spaced to provide an opening, a series of; spaced cutting teeth carried by the inner ends of the walls and formed with"vertically extending cutting,

edges, and coniminutingmeans positioned at justed relatively to each otherthereby aligning or staggering the respective teeth thereof as'desired.

2. A grinding device comprising a hopper section the bottom: of which is formed of two walls'inclined downwardly towards its center and having their inner ends spaced to provide an opening, a lower section having its upper end secured to the bottom of the hopper section and its;botto1nprovided with a restricted discharge opening, aseries of spacedcutting teeth carried by the inner ends of said walls and formed withlvertically extending cutting-edgeaa shaft jo n nalled in said. lower section longitudinally of the opening provided inthe hopper section, a plurality of annular members independently and circuniferentially adjustably mounted on said shaft, teeth formed on said members and having radially; extending cut ting edges adaptedtocoactwith said'vfirst mentionedteeth to form a shearing out, and lnterlocking means-- between said members,

whereby said members, maybeadjnsted relativelyfto each other thereby aligning or stag- 'ering the respectiveteeththereof; as; de-

ture.
